Took the quiz
A sphere is inscribed in a cube with a volume of 64 cubic inches. What is the volume of the sphere? Round your answer to the nearest whole number.
Answer:
the volume of the sphere is
[tex]33.51 in^{3}[/tex]
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, sphere and cube.
Given data
Volume of cube v = 64 cubic inches
since we are dealing with a cube the height and the radius of the sphere is same as the sides of the cube,
we know that volume of cube is expressed as
[tex]v= l*b*h[/tex]
[tex]v=l^{3}[/tex]
[tex]64= l^{3}[/tex]
[tex]l= \sqrt[3]{64}[/tex]
[tex]l= 4 in[/tex]
also diameter d=length l
Diameter d= [tex]4in[/tex]
Radius r = [tex]\frac{d}{2}[/tex]= [tex]\frac{4}{2}[/tex]= [tex]{2 in}[/tex]
Height h=[tex]4in[/tex]
we know that the volume of a sphere is given by
[tex]v= \frac{4}{3} \pi r^{3}[/tex]
substituting into the formula we have
[tex]v= \frac{4}{3} \ *3.142*2^{3} \\v=\frac{4*3.142*8}3} \\v= \frac{100.54}{3} \\v= 33.52in^{3}[/tex]
el volumen de un cubo es de 125 cm3 ¿ cuantas veses aumentara el volumen de ese cubo si se duplica la medida de su arista
Answer: 8 times.
Step-by-step explanation:
I will answer in English:
This says:
The volume of a cube is 125cm^3
How many times the volume will increase if we duplicate the lenght of the side?
If L is the lenght of the side, we have that the volume of the cube is:
V = L^3
If we duplicate the lenght of the side, the new volume is:
V = (2*L)^3 = 8*L^3
So we can see that the volume of the new cube is 8 times the volume of the previous cube.
Now, we can do the math, for our original cube we have:
L^3 = 125cm^3
L = 5cm
the new cube has L' = 2*L = 10cm
The volume of this cube is:
V' = L'^3 = 10cm^3 = 1000cm^3
the ratio V'/V is:
1000cm^3/125cm^3 = 8

Answer:
Denote the two points are A and B, the balloon is C. Then we have,
Side AB = 9 miles
Angle CAB (angle A) = 27 deg
Ange CBA (angle B) = 45 deg
=> Angle ACB (angle C) = 180 - 27 - 45 = 108 deg
Applying the sine theorem:
AB/sinC = BC/sinA
=> BC = AB x sinA/sinC = 9 x sin27/sin108 = 4.3 miles
Denote CH as the height from C to side AB (or distance from ground to balloon), we have:
CH = BC x sin B = 4.3 x sin*45 = ~3.04 miles
=> Distance from ground to balloon: ~3.04 miles
Hope this helps!
:)
Answer:
3.0 miles
Step-by-step explanation:
Let h be the height
Tan(27) = h/b
h = btan(27)
Tan(45) = h/(9-b)
(9-b)tan(45) = h
(9-b)tan(45) = btan(27)
9tan(45) = b[tan(45) + tan(27)]
b = 5.962138633
h = btan(27) = 3.037861367

At a sale, dresses were sold for $90 each. This price was 75% of a
dress's original price. How much did a dress originally cost?
Answer:
A dress originally costs $120
Step-by-step explanation:
To find the original cost of the dress, we will follow the steps below;
let x represent the original cost of the dress
75% of x = $90
[tex]\frac{75}{100}[/tex] × x = $90
[tex]\frac{75X}{100}[/tex] = $90
MULTIPLY both-side of the equation by 100
[tex]\frac{75X}{100}[/tex] × 100 = $90×100
At the right-hand side of the equation, 100 will cancel out 100, leaving us with just 75x
75x = $9000
DIVIDE both-side of the equation by 75
75x/75 = $9000/75
At the left-hand side of the equation 75 will cancel-out 75 leaving us with just x
x= $9000/75
x = $120
A dress originally costs $120

Claire Reagan and Anthony deliver newspapers in the neighborhoods clear deliver 79 papers a day Reagan delivers 2490 papers a month Anthony delivers 616 papers a week how many do they deliver together in a year
Answer:
90,747
Step-by-step explanation:
Clair delivery=79 per day
Total delivery per year=79×365 days
=28,835
Reagan delivery=2490 per month
Total delivery per year=2490×12 months
=29,880
Anthony delivery= 616 per week
Total delivery per year =616×52 weeks
=32,032
Total delivery altogether in a year=28,835+29,880+32,032
=90,747
Answer:
Step-by-step explanation:
Clair delivers 79 papers a day.
Assuming that there are 365 days in a year, it means that the number of newspapers that Clair delivers in a year is
79 × 365 = 28835
Reagan delivers 2490 papers a month. There are 12 months in a year. it means that the number of newspapers that Reagan delivers in a year is
12 × 2490 =29880
Anthony delivers 616 papers a week. Assuming that there are 52 weeks in a year, it means that the number of newspapers that Anthony delivers in a year is
52 × 616 = 32032
Therefore, the number of newspapers that they deliver altogether in a year is
28835 + 29880 + 32032 = 90747
what is the value of x
Answer:
x = 73°
Step-by-step explanation:
a whole circle = 360°
so x + 50° + 91° + 2x = 360°
x+ 2x = 360°- 91° - 50°
3x = 219°
x = 219° ÷ 3
x = 73°

Answer:
if you multiply by powers of 10 then make the decimal point go right.
Answer:
1.23 * 10^-7
Step-by-step explanation:
For decimals smaller than 1 usually something like 0.0000111 you count the decimal places backwards until you get to something greater than 0. So if you have 0.0022 the exponent would be 2.2 * 10^-3
For your problem 0.000000123
There's 6 zeros before you encounter the number thus your exponent is 1.23 * 10^-7

Please help me!! What is x?
Answer:
x = 64
Step-by-step explanation:
90 + x + 26 = 180
116 + x = 180
x = 180 - 116
x = 64
Answer:
x=64
Step-by-step explanation:
x and 26 are complementary, which means they add to 90 degrees.
x+26=90
We want to find x, so we have to get x by itself. 26 is being added on to x. To undo this, subtract 26 from both sides, because subtraction is the opposite of addition.
x+26-26=90-26
x=90-26
x=64
So, x is 64 degrees

When a person is selected at random from a very large population, the probability the selected person has green eyes 0.37. What is the probability that 4 people selected at random all have green eyes? Round your answer to 3 decimal places.
Answer:
0.019
Step-by-step explanation:
Here, we want to calculate the probability that 4 people selected at random have green eyes.
The probability of having green eyes = 0.37
Now, we are selecting 4 people and we want to calculate the probability that all have green eyes
That would be;
0.37 * 0.37 * 0.37 * 0.37 = 0.01874161 which is 0.019 to 3 decimal places
